Strawberry-graphql

-------------------

Fix `requires(fields: ["email"])` and `provides(fields: ["name"])` usage on a Federation field

You can use `requires` to specify which fields you need to resolve a field

python
import strawberry


strawberry.federation.type(keys=["id"], extend=True)
class Product:
id: strawberry.ID = strawberry.federation.field(external=True)
code: str = strawberry.federation.field(external=True)

classmethod
def resolve_reference(cls, id: strawberry.ID, code: str):
return cls(id=id, code=code)

strawberry.federation.field(requires=["code"])
def my_code(self) -> str:
return self.code


`provides` can be used to specify what fields are going to be resolved
by the service itself without having the Gateway to contact the external service
to resolve them.

-------------------

This release adds support for the info param in resolve_reference:

python
strawberry.federation.type(keys=["upc"])
class Product:
upc: str
info: str

classmethod
def resolve_reference(cls, info, upc):
return Product(upc, info)


> Note: resolver reference is used when using Federation, similar to [Apollo server's __resolveReference](https://apollographql.com/docs/federation/api/apollo-federation/#__resolvereference)

-------------------

This release extends the `strawberry server` command to allow the specification
of a schema symbol name within a module:

sh
strawberry server mypackage.mymodule:myschema


The schema symbol name defaults to `schema` making this change backwards compatible.

-------------------

This release adds file upload support to the [Sanic](https://sanicframework.org)
integration. No additional configuration is required to enable file upload support.

The following example shows how a file upload based mutation could look like:

python
import strawberry
from strawberry.file_uploads import Upload


strawberry.type
class Mutation:
strawberry.mutation
def read_text(self, text_file: Upload) -> str:
return text_file.read().decode()

-------------------

This release adds an `export-schema` command to the Strawberry CLI.
Using the command you can print your schema definition to your console.
Pipes and redirection can be used to store the schema in a file.

Example usage:

sh
strawberry export-schema mypackage.mymodule:myschema > schema.graphql

-------------------

This release fixes an issue that prevented using `source` as name of an argument
